Description

TECHNICAL AREA

The present invention relates to a force / path coupling device for fascia / massage / gymnastics rollers, the device being set up to provide a path-dependent reaction force in the event of a pressure force exerted on the device from the outside. The present invention also relates to the use of a coupling that can be arranged on one end face to provide such a force / displacement coupling device in an arrangement coupled to a fascia / massage / gymnastics roller, in particular for visually checking a training / exercise status of a person using the roller . In particular, the invention relates to a device and uses according to the preamble of the respective independent claim.

BACKGROUND OF THE INVENTION

So far, commercially available fascia / massage / gymnastics rolls have been provided for various fitness and health exercises. In particular for exercises relating to the holding and core muscles of people, commercially available fascia / massage / gymnastics rolls are clamped / fixed diagonally or on the same side between an elbow / arm and a knee / leg, for example in a position of the person lying on the back . This can trigger different activation patterns for different muscle chains as well as increased muscular activation. Due to the previous use of such commercially available fascia / massage / gymnastics rollers, however, it is only possible to work / fix against comparatively rigid rollers. This leads to a primarily isometric, immobile muscular activity that does not allow different radii of movement or at least makes it difficult. After analyzing these roles available in the prior art, it has been shown, in particular, that this disadvantageously does not allow a high number of different activated contractile elements to be achieved. Last but not least, the roles available up to now do not allow a good / easy visual inspection by a person (trainer) who controls the exercises. There is accordingly interest in an improved gymnastic training / exercise system for the exercises to be performed with such fascia / massage / gymnastics rollers.

SUMMARY OF THE INVENTION

The object is to provide a gymnastics training device by means of which the execution and control of fitness and health exercises to be performed with fascia / massage / gymnastics rollers can be improved. It is also the task to design a gymnastics training device in such a way that the exercises with such roles can be varied with regard to the force to be applied. Last but not least, the task is to implement or design a gymnastics training device in such a way that the exercises can be controlled in the simplest possible way, in particular from a comparatively great distance.

This object is achieved by a force / displacement coupling device according to claim 1 and by uses according to the independent use claim. Advantageous further developments of the invention are explained in the respective subclaims. The features of the exemplary embodiments described below can be combined with one another, unless this is explicitly denied.

A force / path coupling device for fascia / massage / gymnastics rollers is provided, set up to provide a path-dependent reaction force in the event of a compressive force exerted externally on the device, in particular one of the device in connection with a fascia / massage - / the person using the exercise roll exerted pressure force; According to the invention, it is proposed that the force / displacement coupling device has a coupling on the front side at least on one side and is set up to be / are coupled to a / the respective fascia / massage / gymnastics roller on the front side in an axially aligned alignment, in particular on the front side to a central one Opening or passage or encompassing an outer circumferential surface of the fascia / massage / gymnastics roller on the end face and laterally, the force / displacement coupling device having at least one elastic element, in particular a compression spring or a foam / plastic element, which the path-dependent reaction force (counter pressure) provides over a compression length of at least 3 cm, preferably at least 5 cm in the axial direction. This not only facilitates a more differentiated execution of the exercises by the respective person with regard to the force to be used, but also the control of the exercises can be carried out in a simpler manner, in particular visually with regard to an amount of a momentary compression of the at least one elastic element. For example, a trainer can easily monitor a group of athletes simultaneously without his immediate presence next to the respective athlete performing the exercise being required.

In contrast to this, it was previously not possible to use the rollers available to increase the use of force through a yielding mechanism with increasing resistance. Using the roles available up to now, sports physiology becomes / become In many cases, a too small range of motion and / or insufficient muscular work ensured by the respective exercise. The present invention overcomes these disadvantages.

A coupling device is to be understood here in particular as a device which, on the one hand, makes it possible to ensure a coupling to the roller and, on the other hand, can ensure the correspondingly desired force-displacement coupling. In this respect, the term coupling device also differs from the term “coupling device”, which is restricted to a coupling function. In other words: the coupling device according to the invention has at least two integrated functions, namely coupling to the roller and also providing the path-dependent reaction force, in particular by means of at least one elastic element.

In other words, the device can be coupled to commercially available fascia / massage / gymnastics rollers (or similar gymnastics apparatus), in particular in the form of a fastening attachment. The device, attached / fixed to one or both ends of a commercially available fascia / massage / gymnastics roller, can provide both different radii of movement and a predefinable resistance to movement for trainees. In this way, from a sport-physiological point of view, in particular an increased range of motion and increased muscular work can be achieved. The enlargement of the active range of motion and the increased muscular activity lead advantageously to an increased contractility of the muscles and thus to an optimization of the training stimulus. Every private or commercial user of a commercially available fascia / massage / gymnastics roller and all fitness, therapy and health facilities as well as sports clubs that use commercially available fascia / massage / gymnastics rollers as part of training or therapy can use the device according to the invention, without noticeably changing the training / therapy measures. In particular, by means of the device according to the invention, increased resistance training can advantageously take place in various strengthening and posture exercises in combination with a commercially available fascia / massage / gymnastics roller.

2. II/ alternativ zum Stecksystem: Überzugsystem zum Fixieren/Kuppeln der Vorrichtung an der Faszien-/Massage-/Gymnastikrolle (mit oder ohne Loch), wobei ein dehnbares ringartiges Gummielement (Gummiring-/band) zum Überziehen/Aufstülpen der Vorrichtung auf die Rolle vorgesehen ist (Durchmesser beispielsweise 14cm bis 14,5cm; Länge: 1cm bis 12cm);

III/ alternativ zum Stecksystem oder zum Überzugsystem: Klemmsystem zum Fixieren/Kuppeln der Vorrichtung an der Faszien-/Massage-/Gymnastikrolle (mit oder ohne Loch), wobei ein im Durchmesser dehnbarer Streckring (insbesondere aus Kunststoff) vorgesehen ist (Durchmesser beispielsweise 14cm bis 14,5cm; Länge: 1cm bis 12cm).

The present invention can for example be provided in the following three variants:

1. I / plug-in system for fixing / coupling the device to a commercially available fascia / massage / gymnastics roller (tubular with a central hole), with a variable-size plug (diameter, for example: neck 4.5cm, end 5.5cm; length: 1 to 12cm) ;
2. II / alternative to the plug-in system: Cover system for fixing / coupling the device to the fascia / massage / gymnastics roller (with or without a hole), with an expandable ring-like rubber element (rubber ring / band) being provided for covering / slipping the device onto the roller is (diameter, for example, 14cm to 14.5cm; length: 1cm to 12cm);
3. III / as an alternative to the plug-in system or the cover system: Clamping system for fixing / coupling the device to the fascia / massage / gymnastics roller (with or without a hole), whereby a stretching ring (especially made of plastic) that can be expanded in diameter is provided (diameter for example 14cm to 14.5cm; length: 1cm to 12cm).

The device comprises a resistance mechanism generating the counterforce for the force-displacement coupling, having at least one elastic spring unit (at least one spring element) or at least one deformable foam / plastic unit (diameter, for example, 14cm to 14.5cm; length: 8cm to 12cm). A holder is provided for the spring unit or for the foam / plastic unit, which has a diameter of 14 cm to 14.5 cm and a length of 8 cm to 12 cm, for example. For example, a single foam / plastic cushion has a diameter of 14cm and a width of 1cm to 3cm.

Personified terms, insofar as they are not formulated in the neuter, can apply to all genders within the scope of the present disclosure. Any English-language expressions or abbreviations used here are in each case customary technical expressions and are familiar to those skilled in the English language. For the sake of completeness, any German terms used synonymously / usable are given in (brackets), or vice versa.

According to one embodiment, the compression length of the elastic element is at least 8 cm, preferably at least 10 cm. Last but not least, this facilitates the visual control and also expands the spectrum or the range of possible force variation for the exercising person.

According to one exemplary embodiment, the amount of the reaction force is path-dependent and has a progressive profile, that is to say increases with increasing compression. This type of force-displacement coupling can be advantageous, for example, for performance training and high expenditure of force; for example, this progressive course is ensured by means of at least one compression spring with a progressive characteristic. Alternatively or in addition, springs with a linear characteristic can also be provided.

According to one embodiment, the elastic element is interposed between the coupling and a pressure contact cushion that functions as an interface to the person exercising. Last but not least, this enables a very stable support of the elastic element and an inherently stable design of the device, which is particularly advantageous with regard to the device becoming trapped between the knee (or between the roller) and the elbow, because the person exercising will probably not always be able to meet / contact the center of the pressure contact cushion exactly.

According to one embodiment, the coupling is optionally designed as a plug-in coupling and set up for coupling to / in a central opening, or the coupling is designed as a cover or clamping coupling and is set up for coupling around an outer surface of the fascia / massage / gymnastics roller. Such a type of coupling not least provides the advantage of a very rigid arrangement, especially since the axial length of the coupling can be comparatively large, e.g. 1/4 or 1/3 the length of the roller.

According to one exemplary embodiment, the (inner or outer) diameter of the coupling is designed to be variable / adjustable, in particular by providing diameter setting means on an inner circumferential surface and / or on an outer circumferential surface of the coupling. As a result, the coupling function can also be provided largely independently of the specific diameter of a specific type of roller. The optional diameter setting means are preferably provided in a plug-in system or in a clamping system, the diameter setting means being present, for example, as pulling means extending in the circumferential direction and / or axially aligned reinforcing elements.

According to an exemplary embodiment, the coupling has an extension, in particular a cylindrical extension, which is designed to correspond geometrically to / to a central opening of the roller and is preferably variably adjustable in diameter. This type of coupling favors, in particular, very simple and quick handling, both in terms of assembly and disassembly.

Alternatively, the coupling can alternatively have an elastically stretchable tubular or band-like ring, in particular made of rubber or plastic, in particular a cylindrical extension that is geometrically designed to correspond to an outer surface of the roller and is preferably variably adjustable in diameter. Last but not least, this also favors a power transmission over the entire end face of the roller, i.e. with the least possible pressure on the roller, so that the device can also be released from the roller again relatively easily, which is particularly advantageous for varying exercises.

According to one embodiment, the force / displacement coupling device is essentially made up of only three components connected in series at the end, in particular in an arrangement on a central shaft that can be arranged / coupled axially in alignment with the fascia / massage / gymnastics roller: pressure contact cushion, elastic spring element , Clutch; with an interposed retaining disk for homogenization / area distribution of the force transmission (minimization of pressure force peaks), which can optionally also be integrated in the coupling and / or in the pressure contact pad, is optionally provided on the two end faces of the spring element. Last but not least, this provides a simple and robust structure which is also advantageous, for example, with regard to exchanging / changing the elastic element. The optional retaining washers can also promote contact / contact over the full surface area possible.

The components described here are preferably arranged on a central shaft which, for example, can be pushed together telescopically (telescopic shaft), in particular in a section between two mounting disks. The at least one elastic element is arranged in the section of the sheep and counteracts compression. The shaft has, for example, a tube-in-tube arrangement in which the extraction movement of the tubes against one another is blocked at a stop. The stop position can optionally be adjusted so that the pretensioning of the elastic element can be set or the elastic element can be exchanged / changed in a simple manner even if the size varies.

The shaft can optionally be subdivided, in particular for the purpose of dismantling the elastic element. Optionally, a / the retaining disk and / or the coupling and / or the pressure contact pad can also be dismantled, so that an alternative elastic element can be mounted in a simple manner. For this purpose, e.g. a locking mechanism can be provided in each case.

According to one embodiment, the device has a cylindrical outer contour, in particular an outer contour adapted in diameter to the fascia / massage / gymnastics roller. Last but not least, this also favors intuitive handling, in particular since the device is frontally attached to the in any relative angular / rotational position Role can be coupled. The device is preferably even designed to be rotationally symmetrical.

The above-mentioned object is also achieved by a force / distance training device having a fascia / massage / gymnastics roller and at least one force / distance coupling device coupled to it according to an embodiment described above. In this way, the aforementioned advantages can be realized, in particular with regard to the provision of a set of rollers and devices that are matched to one another in particular in terms of geometry.

The above-mentioned object is also achieved by using a coupling which is arranged / can be arranged on one end face to provide a force / path coupling device, in particular a force / path coupling device described above, in a to a fascia / massage / gymnastics roller Coupled arrangement for providing a path-dependent reaction force in the event of a pressure force exerted from the outside on the device; The coupling is coupled to the device at the end in an axially aligned alignment, in particular at the end to a central opening or passage or at the end and laterally encompassing an outer surface of the fascia / massage / gymnastics roller, the path-dependent reaction force over a compression length of at least 3 cm being preferred at least 5cm in the axial direction by means of at least one elastic element, in particular by means of a compression spring or a foam / plastic element, is provided, the at least one elastic element on a central shaft axially aligned with the device between the coupling and an interface to the training Person acting pressure contact pad is / is arranged. In this way, the aforementioned advantages can be realized, in particular with regard to training with a variable pressure force that can be easily dosed and with regard to a visual check of the manner in which the exercises are carried out.
